Figures 2(a) and 2(b) show the results for a batch distillation column operating at constant reflux ratio of 2.0 with ten theoretical stages. In Figure 2(a) it is observed that at the bottom of the column, the composition of benzene decreased with time while the composition of the heavy components increased.arolo and Guarice [ 8 ] extended their continuous short-cut method to batch distillation columns and used an infinite stage column. Seader and Henley [ 9, 10 ] applied Sundaram and Evans [ 3 ] method and showed how the FUG equations were used to solve a simulation problem with constant reflux.
Executive Summary on Persistence and Retention Topics. â¢ Retention rates commonly measure the percentage of freshmen that re-enroll the next academic year as sophomores. The primary reason that retention rates, along with graduation rates, are important is that retention rates are. perceived as indicators of academic quality and student success. â¢ In addition to retention, persistence, a studentâs continuation behavior leading to a desired goal, helps describe.
Increases Morale. Employees that enjoy what they do and the atmosphere in which they work are more likely to remain employed with their company. Retention strategies are important because they help create a positive work environment and strengthen an employeeâs commitment to the organization. Strategies that target employee engagement, such as team-builders and community involvement, increase company morale and give employees a sense of pride in what they do.
